The Millennium Galaxy Catalogue: Galaxy Bimodality [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractGalaxy bimodality is caused by the bulge-disc nature of galaxies as opposed to two distinct galaxy classes. This is evident in the colour-structure plane which clearly shows that elliptical galaxies (bulge-only) lie in the red compact peak and late-type spiral galaxies (disc-dominated) lie in the blue diffuse peak.

A Heuristic Evaluation of Partitioning Techniques Considering Early-Type Galaxy Databases

open access: yesEngineering Proceedings, 2023
Galaxies are one of the most interesting and complex astronomical objects statistically due to their continuous diversification caused mainly due to incidents such as accretion, action, or mergers. Multivariate studies are one of the most useful tools to

On the Incompleteness of Birkhoff’s Theorem: A New Approach to the Central Symmetric Gravitational Field in Vacuum Space

open access: yesReports in Advances of Physical Sciences, 2023
Birkhoff’s theorem (1923) states that in the framework of General Relativity the only solution to the central symmetric gravitational field in vacuum is the Schwarzschild metric.

Meniscus Root Tear: Extended Classification and Arthroscopic Repair Techniques

open access: yesArthroscopy Techniques
The meniscus root is an attachment of the anterior and posterior horns of the meniscus onto the tibia, and its primary function is to prevent extrusion under axial load. Meniscus root tear constitutes 15% to 20% of meniscus tear.

Wedge-less V-Shaped Distal Femoral Osteotomy Through Lateral Approach to Correct Valgus Malalignment

open access: yesArthroscopy Techniques
Coronal-plane deformities of the knee are prevalent skeletal abnormalities in the adolescent population. Although valgus alignment is observed less frequently than varus alignment, it predisposes patients to several pathologic sequelae, including ...

Galaxy–galaxy lensing in the VOICE deep survey

open access: yesAstronomy & Astrophysics, 2022
The multi-band photometry of the VOICE imaging data, overlapping with 4.9 deg2of theChandraDeep Field South (CDFS) area, enables both shape measurement and photometric redshift estimation to be the two essential quantities for weak lensing analysis. The depth of magABis up to 26.1 (5σlimiting) inr-band.

First detection of galaxy-galaxy-galaxy lensing in RCS [PDF]

open access: yesAstronomy & Astrophysics, 2008
The weak gravitational lensing effect, small coherent distortions of galaxy images by means of a gravitational tidal field, can be used to study the relation between the matter and galaxy distribution. In this context, weak lensing has so far only been used for considering a second-order correlation function that relates the matter density and galaxy ...
